In corn, the following allele pairs are on chromosome 9:colored (C) vs. white (c)aleurone color; starchy (Wx) vs. waxy(wx) endosperm; and full (Sh) vs.shrunken (sh) endosperm. F1 plantsheterozygous for all three alleles were test crossed; the resultingprogeny had the following phenotypic ratios:
colored, waxy, shrunken 116
colored, starchy, full 601
colored, starchy, shrunken 2538
white, starchy, shrunken 4
white, starchy, full 113
white, waxy, full 2708
white, waxy, shrunken 626
colored, waxy, full _____2
6708
Determine the order of and distances between the threegenes.  Also determine the coefficientof
coincidence (C) and the interference (I).
